Well it was when I was a kid. Town gas / coal gas was roughly 50% hydrogen. So it seems pretty likely that the pipe network is up to snuff, or could be with relatively little work. To use in central heating the burners would no doubt have to be changed, but we did that before, remember, when all...

Hydrogen fuel cells are by no means ignored. For heavy transport (lorries, trains, fixed-base things like cabs) they will probably be the solution. But they will not be effective in reducing CO2 emissions until hydrogen is made from renewable energy and water electrolysis or some chemically...

No this is wrong. Wind power with big turbines produces their manufacturing energy in less than a year, Silicon solar cells are not so good but manage 3 - 5 years to repay their energy, and they have a lifetime of 20 - 25 years. I haven't checked the ERoEI site but I did the sums and research...

Thanks very much for your experience and advice, Pete. Here they seem to use shorter piles but more of them, but then we don't have a frost line to deal with. I couldn't pick your beams up! Keith

The deWalt is a really good thicknesser. Worth getting a jig to regrind blades. I have a Tormek one and it pays for itself quite quickly.

It's a good thought thanks, James, but I don't have access to get them in, not without a crane that could lift them over the house and into the back of the garden. Keith

I am hoping to be able to build a new, larger workshop in the spring, so am starting the design thoughts and would like comments. I have some constraints. - the site available is 5.5 x 4.5 m, perhaps 5.5 x 5.5 (external) if I go for planning permission and go right to the boundary. I don't think...

Thanks for the update, Beech. Very interesting to see how you have coped, and I hope that brutal workload is getting under control. Congratulations on working on a succession plan and for pulling the company through this tough time. In my case, I just work a day a week as chief scientific...

I use and like French cleats. I use 250 or 500mm length 'modules' for the holders, which makes it even easier to swap things round. Rarely does one build and finish a workshop permanently. Mine is still developing after 25 years, and layout is very different from when I started. Most of the tool...

I think a number of repliers have made assumptions about UK flats, which are built far more flimsily than in central Europe. I used to have a flat on the third floor in Prague, in a 1910 building that was built like a fortress. Floors were concrete covered with sand and then parquet. Amazingly...

Tewkesbury Saw do a good job by mail. I've had tenon saws, rip saws and circular saw blades (plate and TCT) done by them, nice jobs.

I'd be happy to turn you up a brass bush, it's a small job. But I would need the mating parts. Doing it by dead reckoning is dodgy!

Looks like you need to look for 'constant force spring', though I don't know if you will find the identical one, may need to adapt it. For example...

There should be a reversing lever in the gear train that will select forward/neutral/reverse. It may the the plunger at the bottom left of the first picture. For right hand threads (or slow feeds from right to left) the tool moves from right to left (towards the headstock) when the drive is...

I think the only difference that leather would make is a different glue, again with fibre filling. I suggest you browse for conservation supplies. You'll still need backing paper to hold it together.

Thanks for reporting back. That's a really nice job! Good stain match, too.

And have fun with that Stanley shooter, it's a gem!

Tom, that's an amazing machine! Hope you get it sorted!

Yes, I'd say weeks too depending on the formulation. Best finish ever though. I did use some in the USA which dried quite quickly and has lasted very well. I've never found the equivalent here. I think it was maybe boiled, but not sure.

I would not take it off the frame as it is another major repair to put it back. Initially it would probably;y be put on samp then shrinks to fit. You can't do that again. I would certainly do lots of reading and practice before attempting the real thing. Make sure you use reversible adhesives...
